We are trying to design an addition to our home. It will be a master-bedroom and deck built off of the kitchen. Does the roof have to conect horizontily to the main house, or can the roof conect at a lower point which will create a "V" like formation at the seam?

Devon:
Not really sure about your question (not being able to see what you have in mind), but the short answer to your question would involve 2 things -the local building code and what material you're planning to use for the new roof.
If the addition roof is going to be flat (horizontal) you can't use standard shingles. Shingle manufacturers require a minimum roof pitch (slope) of 3/12 before they will warranty their product. Most building codes specify the same. That is, the roof must slope at an angle so that there is a minimum of a 3 inch drop for every foot of rafter.
The answer as to whether you can use either a flat roof or shingled roof is in the existing structure as well as your local building codes.

If I understand your question, the ridge (peak) of the addition roof can run either perpendicular or parallel to the existing roof. If you run it perpendicular, it will drain rain water more easily without any extra work. If the addition roof runs parallel, then you would need to build a "cricket" with a ridge that runs perpendicular to both the existing and the addition roofs. Drive around your town and look at roofs... you are almost certain to find a roof of similar configuration and be able to adapt the idea to fit your situation.

Devon: Y ou can actually do it either way. both the previous answers are correct. But if you have a roof less then a 3/`1 picth, you can use a product called sure seal. It comes in rolls. It will absolutly seal your roof. Then you can apply 3 tab or rolled roffing on it. You can also apply a rubber roof. I would recommend a roof that runs perpendicular to your existing roof. It will make your home look better. Shed roofs can sometimes look tacky. Good Luck, Jack the Contractor
